A while back, I had F4 installed on my D drive. I had a drive issue, and had to replace said drive. I was able to copy the folder over to the new drive, and I assumed all was well. I have recently begun to get my flight sims up and running again( my first love...), but I can't uninstall nor reinstall F4AF. I keep getting an invalid drive message, then the installer quits. I assume it's a registry issue, but I have registry mechanic. I have also tried the Windows Installer cleaner, but that didn't help either. Could someone help please? THANKS.

You said you copied the folder over to the new drive. Was this before or after you attempted the reinstall?

Are you running the installer in "Administrator" mode? Browse to the CD/DVD drive, right-click the .exe and "run as administrator."

I think I may have it. Turns out there are two copied folders in my G drive. One is G:/program files/Leadpersuit. The other is G:/programfiles/Battlefield Operations. They are either conflicting with each other, or the path is incorrect( BIG DUMMYHEAD!!!!)I'll delete both folders, and see if that helps( I seem to remember the correct path was g:/BattlefieldOperations/Lead Persuit?)

yes thats the one *:/Program files(x86)/lead pursuit/Battlefield operations/
